A routing metric is a measure used by a routing protocol to select a best path, without a routing metric a protocol will not know which path to use to send a packet. A number of routing metrics exist for WMN, but routing still remains a problem for WMN. The routing metrics have not been compared with QoS parameters. This paper is a work in progress of the project in which the authors want to compare the performance of different routing metrics in WMN using a wireless test bed. They selected four routing metrics to be evaluated. Evaluation will reveal the best routing metric for WMN, if there is none, it will help one recommend design criteria for an optimal routing metric for WMN.
